So this is my first mod and my first time making a brass breech.
I originally posted this on /r/nerf and was told to post up here to. The blaster was fantastic out of the box, but I was really motivated to see what it could do and the internals didn't scare me anywhere near what most other blasters do. I made a ton of mistakes but learned a lot in the process, The end product is a lever action blaster that is crazy easy to prime that pulls mid 120's to high 130's.
After looking through Van's Sentinel guide (which I just found.... man do I wish I had looked at that before doing this mod!), if I were to do this again, I'd say skip the brass breech. It definitely lowers the rate of fire like crazy and I'm interested in getting another one and popping in the [k26] just to see how things change.
Here's the video. Let me know how else you think it can be improved.
